Tom, Thanks for sharing this. I don't know if it was mentioned before, but for those that are interested, these agraffes do not have straight through holes like current plate agraffes. The holes go through the agraffe at an angle (angled with reference to the string plane, or another way to say it, the holes on one side of the agraffe are higher above the bridge than the holes on the other side of the agraffe) so the string takes an upward or downward jog from one side of the agraffe to the other. Alternate agraffes are reversed. One agraffe will be oriented so that the string takes an upward jog and on the next note the agraffe will be reversed so that the string makes a downward jog. The string taking a jog like that puts a rolling moment on the agraffe. I think the idea is that by reversing the direction of the jogs on every other agraffe the net rolling moment on the bridge is zero. Someone, I believe Clark, mentioned that some of these pianos have typical notched and pinned bridges in the top section. Was this piano like that or did the bridge agraffes go all the way to the top?
